ZOLL Medical Corporation

ZOLL Medical Corporation, founded in 1980, is a global leader in acute critical care and diagnostic software solutions. The company provides innovative medical devices and software designed to diagnose and treat patients suffering from serious cardiopulmonary and respiratory conditions. ZOLL’s products, including defibrillators, cardiac monitors, and CPR feedback devices, are used worldwide in hospitals, emergency services, and military settings.
